CARRIAGE-AXLE.

QPECIPICATIQN forming part of Letters Patent No. 317,305, dated May 5, 1885.

Application filed November 21, 1884.

To all whom it may concern.-

Be it known that 1, PETER COOL, a citizen of the United States, residing in the city of Manhattan, in the county of Riley and State of Kansas, have invented certain new and useful Improvements in Axles; and I do hereby declare the following to be a full, clear, and exact description ofniy invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to that class of axles for vehicles which are provided with antifriction rollers set in seats or grooves formed in said axles forlcssening friction, and consequently reducing the power required'to move or propel such vehicles.

The object of the invention is to provide simple and effective devices for fitting the anti-friction rollers in axles and firmly holding them in place.

To these ends my invention consists in certain details of construction and combination of parts, as will be more fully understood by reference to the accompanying drawings, in which- Figure 1 is a longitudinal View of an axlespindle whereinl is a dovetail groove, as represented in Fig. 5, which is a transverse sec tion of the same, and e is a block fitted to the said groove Z, placed in the outer end thereof, and held in position by the pin it. Fig. 2 is a longitudinal View of an axle-spindle with my invention complete and in position, wherein a is a block fitted to said grooveZ and slid into position before the other parts; next a slide, represented in isometric projection by Fig. 7, being of the same length as and as a bearing for the roller, also represented in isometric projection by Fig. 6, said slide grooved so as to allow said roller to freely revolve therein, is slid into said groove Z to said block a; then b, a roller of proper size to easily revolve within said groove Z, is slid into position immediately over said slide; next a, another block fitted to said groove Z, another slide, Fig. 7, and d, another roller, are slid into their respective po- (No model.)

sitions in said groove Z; and, lastly, said block 6 is slid into position and the pin is put in place. 7

The roller-journalsi may be attached to the said blocks and the journal-bearings made in the rollers, or the reversethat is, the rollerjournalsi may be attached to the rollers and the journal-bearings made in the blocks, as deemed most advisable.

Fig. 3 is a transverse section of said spindle when out through the rollersb or d. n represents said roller. Fig. 4 is a transverse sec tion of said spindle when out through said blocks (L c or e.

m represents a block.

Fig. 5 is a transverse View of the axle, showing its groove. Figs. 6 and 7 are perspec tive views of the roller and the slide.

One or more rollers may be used, but I have, for the purpose of better explaining my invention, here represented a spindle with two rollers. When but one roller is used, the block 0 of course is omitted, and the remaining parts lengthened sufficiently to fill the groove Z.

The parts a b c d and e are made flush with the outside of the spindle.

I deem it preferable to make but one groove Z, and that on the under side of said spindle, where the bearing is heaviest. on the inside of the hub of the wheel; but two or more such grooves may be made in each spindle and provided with the parts, as described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent,is

In combination with a carriageaxle having a longitudinal dovetail groove, the thrust or bearing blocks, the sliding plate having a concave surface, and the roller fitted on said plate and mounted on the bearing-blocks, substantially as described.

PETER COOL.
